Unfortunately there can be no doubt that man is, on the whole, less good than he imagines himself or wants to be. Everyone carries a shadow, and the less it is embodied in the individual’s conscious life, the blacker and denser it is. If an inferiority is conscious, one always has a chance to correct it. Furthermore, it is constantly in contact with other interests, so that it is continually subjected to modifications. But if it is repressed and isolated from consciousness, it never gets corrected.

On the Internal Battle in the Soul
We know that the wildest and most moving dramas are played not in the theatre but in the hearts of ordinary men and women who pass by without exciting attention, and who betray to the world nothing of the conflicts that rage within them except possibly by a nervous breakdown. What is so difficult for the layman to grasp is the fact that in most cases the patients themselves have no suspicion whatever of the internecine war raging in their unconscious. If we remember that there are many people who understand nothing at all about themselves, we shall be less surprised at the realization that there are also people who are utterly unaware of their actual conflicts.
